Abstract (en)
Paste (A) comprises a solid phase containing at least a nanoparticulate powder (30-95 wt.%) and a liquid phase (at least 5 wt.%) containing at least a dispersing agent, where (A) contains less than 3 wt.% of water and the liquid phase contains less than 10 g/l of volatile organic compounds (VOC). Independent claims are included for: (1) the preparation of (A) comprising forming the nanoparticulate powder, and dispersing the nanoparticulate powder, continuously or in portions, into the liquid phase; (2) a dispersion in (A) and one or more solvents; and (3) the preparation of the dispersion comprising mixing (A) by stirring or shaking with a solvent or its mixture.
